Pion photo- and electroproduction on nucleons in relativistic chiral perturbation theory

2022

En esta tesis, hemos estudiado la producción de piones mediante pruebas electromagnéticas en nucleones. Para cada uno de los estudios realizados aquí, nos enfocamos en la Teoría Quiral de Perturbaciones (ChPT) relativista para hadrones ligeros: nucleones, piones y los grados de libertad explícitos Delta. Para preservar la covariancia de la teoría, se implementó el método de renormalización en el esquema Extended On Mass Shell (EOMS). En este caso, las divergencias y los términos que violan el conteo de potencias se absorben en las constantes de baja energía (LECs) del Lagrangiano efectivo. El presente trabajo se desarrolló dentro de tres estudios principales relacionados con la producción d…

Planning Production Preparation Processesusing The Critical Chain Method

2017

This paper explains the usefulness of critical chain project management for planning production preparation processes. A synthesis of issues of project management and production preparation processes is presented, and a conceptual model of concurrent design processes using the critical chain method is developed. The proposed model of planning production preparation processes enables improving the effectiveness and economic efficiency of new product development. The main assessment indicators of efficient project management in production preparation are: shortening the preparation time of new product development, rational use of resources, and reducing the risk of failure. The proposed appro…

“Reclaiming public spaces”: Individuazione di strategie e metodi per la partecipazione della cittadinanza attiva nella produzione e gestione di spazi…

2014

A partire dall’analisi di due casi studio di (ri)appropriazione e riconversione temporanea a fini “pubblici” di aree inutilizzate, quali le appropriazioni/(ri)appropriazioni dell’ex-aeroporto di Tempelhof a Berlino e del “laghetto” in via Prenestina a Roma, l’articolo si propone di esplorare alcuni interrogativi quali: E’ possibile costituire una alternativa reale alla riduzione/sostituzione dello spazio pubblico, dovuta in gran parte ai problemi di bilancio che minacciano l’operatività delle amministrazioni locali, valorizzando le esperienze di auto-organizzazione, auto-gestione e partecipazione emerse nelle nostre città? Come interpretare/tradurre in strategie e metodi operativi la pressa…

Virtualization of work in global supply chains

2016

ABSTRACT. Background: The paper is devoted to the notion and benefits of implementing virtual work in global supply chains. Virtual work must be understood as an intentional activity of a human being, aimed at rendering services (tangible and intangible), by means of ITC tools, performed in a distance from the traditional place of work, in a mobile manner. The empirical research were conducted on the basis of 4 case studies of global leaders of supply chains, which in accordance with M. Fisher's classification, represent two types. The case studies confirmed the positive influence of virtual work both in effective and flexible supply chains. Favourable market and technological conditions an…

Simultaneous optimization of harvest schedule and measurement strategy

2013

In many recent studies, the value of forest inventory information in the harvest scheduling has been examined. Usually only the profitability of measuring simultaneously all the stands in the area is examined. Yet, it may be more profitable to concentrate the measurement efforts to some subset of them. In this paper, the authors demonstrate that stochastic optimization can be used for defining the optimal measurement strategy simultaneously with the harvest decisions. The results show that without end-inventory constraints, it was most profitable to measure the stands that were just below the medium age. Measuring the oldest stands was not profitable at all. It turned out to be profitable t…

Teaching programming by emphasizing self-direction: How did students react to the active role required of them?

2013

Lecturing is known to be a controversial form of teaching. With massed classrooms, in particular, it tends to constrain the active participation of students. One of the remedies applied to programming education is to use technology that can vitalize interaction in the classroom, while another is to base teaching increasingly on programming activities. In this article, we present the first results of an exploratory study, in which we teach programming without lectures, exams, or grades, by heavily emphasizing programming activity, and, in a pedagogical sense, student self-direction. This article investigates how students reacted to the active role required of them and what issues emerged in …
